摘要: Abstract The impact of excitation intensity on the Stokes and anti-Stokes luminescent properties Nd3+ ions in stoichiometric LiNdP4O12 nanocrystalline powders was investigated. fluorescence spectra relative intensities were strongly affected by power at double 808 830 nm. decay became nonexponential shortened with pumping increase. efficient up-conversion under strong 808 nm observed visible range four bands assigned. raising a remarkably long time constant equal to around 1 s, which decreased
